The Surveillance NAS Faceoff – Seagate Surveillance Hard Drives Vs WD Purple Surveillance Drive – Which one is the safest purchase?

Surveillance and NAS Drives

It has long been a use of modern Network Attached Storage, or NAS, as a means of achieving first class home and business Network Video Recording (NVR). Indeed the big NAS brands Synology and QNAP have gone to great lengths to proclaim their NAS server units ability to function beautifully as accessible and often stand-alone NVR machines. Both vendors have included IP Camera Licences with their software in an effort to convince people to make the leap to NAS based NVR and additional licences being sold cost effectively to maintain the cost of the numerous services required – SMS support, customer service, linking pre-existing setups to your own. When it comes to buys a NAS with CCTV and Surveillance as your chief use, then QNAP NAS and Synology NAS will be the first choice for you.

It is what is inside the NAS that counts…

 However choosing the right NAS for Surveillance NVR needs is only the first part. Next you have to consider the media you intend to install inside. Now, if you have money to spend, you can always go for the most reliable and fastest form of digital media, Solid State Drives (SSD). However this will work out astronomically more expensive, even with SSD prices slowly coming down and you will more than likely spend somewhere around £1 for every 5-6 Gigabytes for SSD. So, many choose the more traditional route with Hard Drives. When it comes to Hard Drives though, these days you afford to be quite choosey. The big brands like Western Digital, Seagate and HGST all offer different hard drives that are tailored to specific purposes and therefor you can buy Surveillance media that will perform to the highest standard.
